The Bi-Metallic is a silver, gold, molybdenum, tungsten, and copper mine located in Okanogan county, Washington.
About the MRDS Data:
All mine locations were obtained from the USGS Mineral Resources Data System. The locations and other information in this database have not been verified for accuracy. It should be assumed that all mines are on private property.

Satelite View
MRDS mine locations are often very general, and in some cases are incorrect. Some mine remains have been covered or removed by modern industrial activity or by development of things like housing. The satellite view offers a quick glimpse as to whether the MRDS location corresponds to visible mine remains.

Comments
Comment (Location): 3 MILES NORTHEAST OF HAVILLAH
Comment (Deposit): DEVELOPMENT CONSISTS OF SEVERAL SHAFTS AND TWO ADITS. A TOTAL OF 2200 FEET OF LINEAR TRENCHING WAS DONE BY THE U.S. BUREAU OF MINES (USBM) IN 1945 TO DETERMINE THE EXTENT OF MINERALIZATION; NO SIGNIFICANT MINERALIZATION WAS FOUND. ASSAYS OF SAMPLES FROM THE ADIT BY THE USBM RANGED FROM 2.20 TO 3.87% MO AND 0.03 TO 0.32% CU AND SHOWED TRACES OF AU AND AG. SAMPLES TAKEN FROM THE TRENCH AVERAGED 0.32% CU; TRACE AMOUNTS OF AU AND AG WERE FOUND IN SOME SAMPLES. SAMPLING SUGGESTS THAT THE BETTER COPPER VALUES ARE FOUND IN SAMPLES FROM NEAR THE SURFACE, WHEREAS THE HIGHER MOLYBDENUM VALUES ARE FROM SAMPLES COLLECTED AT DEEPER LEVELS IN THE MINERALIZED SYSTEM (MOEN, 1980, P. 57). ; INFO.SRC : 1 PUB LIT
Comment (Geology): THE DEPOSIT IS WITHIN THE ALKALIC COMPLEX OF BIMETALLIC MOUNTAIN, WHICH IS OF CRETACEOUS OR TERTIARY AGE. THE MONZONITE, WHICH IS BRECCIATED AND LOCALLY INCLUDES SKONKINITE, IS INTRUDED BY HYDROTHERMALLY ALTERED, FINE-GRAINED, ALASKITE DIKES. THE ROCKS INTRUDE METASEDIMENTARY ROCKS OF THE SPECTACLE FORMATION OF THE PERMIAN ANARCHIST GROUP, WHICH ARE LOCALLY HORNFELSED (STOFFEL, 1990).
Comment (Production): HIGH GRADE COPPER ORE WAS SHIPPED FROM ONE OF THE SHAFTS IN 1918 (MOEN, 1980, P. 57).
